Wow, a lot has changed since last time I was here! I'm hoping that I've come to the right place for information regarding the clutch in my bands coach. Months ago, we lost he clutch in our 1968 GM 4903 (4-speed). We managed to get our hands on three new clutch plates for it, but as the mechanic is now finally getting us back on the road, he has a question about the thickness tolerances of the steel plates within the clutch plates. My mechanical knowledge is limited regarding clutches, but I'm assuming these are some type of pressure plate. Our mechanic is telling me that the plates in question are in poor shape, but could possibly be turned by a machinist, IF there is enough tolerance left. Keep in mind that we are a band, and on a limited budget. Between the clutch plates and towing, we've already got $1100 tied up. In hindsight, we should have towed it to our regular mechanic, but we were led to believe our current guy had all kinds of experience with this type of thing and we'd be back rolling in no time. Any information that could be offered to help us get past this fiasco is GREATLY appreciated! I've been put in charge of making the magic happen, and this board seems to be a gold mine of information.
